Unlink Event
Fires when the OS wants to unlink (delete) a file.
Syntax
type TUnlinkEvent = procedure ( Sender: TObject; const Path: String; var Result: Integer ) of Object;
property OnUnlink: TUnlinkEvent read FOnUnlink write FOnUnlink;
Remarks
This event fires when the OS has decided to delete the file specified by Path.
The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a negative error code value (e.g. -ENOENT to indicate that the file does not exist) to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
Windows: the resulting error value is ignored due to the OS design.
